The powder-blue panchax, Pachypanchax omalonotus, is a killifish from Nosy Be and the adjacent Sambirano River system in northwestern Madagascar. Many fish in the hobby identified as P. omalonotus are in fact P. arnoulti, as are those in much older aquarium literature, and a degree of hybridisation has undoubtedly occurred. Metallic gold spots on the flanks separate it from that species, and males are polymorphic, with yellow, red and blue morphs in different populations.
